Heyho
I am searching now for 2hours onthe internet, just to find a good documentation for EAN128.
After some wasted time I found a declaration for a bit-array in C, but I finally don't understand everything.

So far, so good, but I don't really see, when do I need the different Codes? If I have a string with a content like "1234567ABCD"- when and why is it necessary to change the code?

Thanks and gr33ts,
Marc Giesmann

Is this of any help? http://en.wikipedia.org/wiki/GS1-128

Okay, this is about the standard, but not about the charset and it's use. I'll try to make my own solution...

Suggestions are very welcome

If what you want to do is print the barcode, there should be all kinds of software already available... eg a 'barcode font' file. You just set the font and the size and print normally.

Depending on what you want (Product label, Consumer package label, SSCC-14 or -18 shipping container label), you may have to build the character string yourself, but that's pretty well-documented how to do that for each type of identifier.

Note also the terms "EAN" and "UCC" and "SSCC18" and "UPC" and "Barcode" and the like tend to get thrown around pretty loosely, so getting accurate info from the user re "what he really wants" may prove a bigger challenge than coding it.

I found http://www.barcodeisland.com to be a useful resource.
